The square of a number, x, is 16 less than eight times the number. What is the number?

9514 1404 393

Answer:

Step-by-step explanation:

Let w represent the width. Then the length is 2w-5, and the perimeter is ...

  P = 2(L+W)

  44 = 2((2w-5) +w)

  44 = 6w -10

  54 = 6w

  9 = w

  2(9) -5 = 13 = length

The length of the rectangle is 13 meters; the width is 9 meters.

Answer:

Use the formula S=√A.

We have to determine,

The length of each side of his patio.

According to the question,

Chip has enough concrete to pave a square area of 200ft^2 for a backyard patio,

To obtain the length of each side of patio using the given formula.

Formula; [tex]S= \sqrt{A}[/tex]

Where, [tex]A = 200ft^2[/tex]

Substitute the value of A in the given formula,

Answer:

12 and 53

Step-by-step explanation:

let 'x' = one number

let 'y' = other number

System of Equations:

x + y = 65

x - y = 41

Substitution Method:

x = 41 + y

41 + y + y = 65

2y = 24

y = 12

Answer:

x = 12

Step-by-step explanation:

We will be using pythagoras theorem.

Therefore, we will have: [tex]a^{2}[/tex] + [tex]x^{2}[/tex] = [tex]13^{2}[/tex]

Moreover, we have: [tex]a^{2}[/tex] = [tex]4^{2} + 3^{2}[/tex] => [tex]a^{2}[/tex] = 25

=> 25 + [tex]x^{2}[/tex] = 169

=> [tex]x^{2}[/tex] = 144 => x = [tex]\sqrt{144}[/tex] = 12

Answer:

208m²

Step-by-step explanation:

Okay, so you can split this abomination into a rectangle, another rectangle, and a square, so we're going to start with the rectangle to the far left:

The formula for the area of a rectangle or square is length x width, so we just have to plug:

4 x 8 = 32

Now we do the next rectangle, but we have to figure out the length first, so:

4 + 4 = 8

Now we plug:

8 x 4 = 32 (I now realize that the rectangles are even and we could've just multiplied the first one by two, but it's always good to check)

Now we do the square:

12 x 12 = 144

Now we add it all together:

32 + 32 + 144 = 208

So the area of the figure is 208m²

Answer:

596

Step-by-step explanation:

Each term of the arithmetic sequence is 9 greater than the previous term.

Since the first term is 29, then 29+9 = 38, the second term in the sequence.  Likewise, the third term, 47, is 9 greater than the previous term, 38.  47 is also 2(9) greater than the first term, 29.

Therefore, finding the 64th term in the sequence would be the same thing as adding 9 to the first term (29) a total of n-1, or 64-1 times. Instead of adding, one can simply multiply 29 by 63, since 64-1 = 63.

29 + 63(9)

= 29 + 567

= 596

So, the 64th term of the arithmetic sequence is 596.

Answer:

  the correct choice (A) is marked

Step-by-step explanation:

The function g(x) is translated 3 right and 1 down from f(x).

The transformation ...

  g(x) = f(x -h) +k . . . . . . translates h right and k up

For your translation, you have (h, k) = (3, -1). Putting those into the transformation model above gives ...

  g(x) = (x -3)² -1 . . . . matches choice A

Answer:

the number of miles did he drive the truck is 276 miles

Step-by-step explanation:

The computation of the number of miles did he drive the truck is as follows

Let us assume the mileage be m

Now according to the question

0.8m + 18.99 = 239.79

0.8m = 239.79 - 18.99

0.8m = 220.8

m = 276

Hence, the number of miles did he drive the truck is 276 miles

The above represent the linear equation

and

18,333,000

Answer:

6871000

18333000

Step-by-step explanation:

all the numbers before thousands will be zeros and the number that decide whether thousands will be added one or remains the same is the number before the thousands which is hundreds, if it's 0-4 that means the thousands remain the same at it was before and all the numbers before it become zeros, but if it's 5-9 that means thousands will be added one and all the numbers before it become zeros.

Answer:

The sum of the first ten terms is -35.

Step-by-step explanation:

The first term of an arithmetic sequence is 10, and its common difference is -3.

We want to find the sum of the first 10 terms of this sequence.

Remember that the sum for an arithmetic sequence is given by:

[tex]\displaystyle S=\frac{k}{2}\left(a+x_k\right)[/tex]

Where k is the number of terms, a is the initial/first term, and x_k is the last term.

Since our initial term is 10, a = 10.

And since we want to find the sum of the first ten terms, k = 10.

So, we will need to find the last or tenth term. We can write an explicit formula. The standard explicit formula for an arithmetic sequence is:

[tex]x_n=a+d(n-1)[/tex]

Where a is the initial term and d is the common difference.

So, by substituting, we acquire:

[tex]x_n=10-3(n-1)[/tex]

Then the tenth or last term is:

[tex]x_{10}=10-3(10-1)=10-3(9)=10-27= -17[/tex]

Then the sum of the first ten terms will be:  

[tex]\displaystyle S_{10}=\frac{10}{2}(10+(-17))=5(-7)=-35[/tex]

Answer:

-35

Step-by-step explanation:

[tex]a_{1}[/tex] = 10+(-3)(0) = 10

[tex]a_{10}[/tex] = 10+(-3)(9) = -17

[tex]S_{10}[/tex] = 10[(10 -17)/2] = 10(-7/2) = -70/2
